Patent GB-2257850-A (GB)
Title: Casing for electrical connections.
Inventor: HOLLICK DAVID JOHN
IPC: H02G15/113
Filed: 1992-06-17
Abstract: A casing for electrical apparatus comprises a pair of hollow body parts (10, 11) each of which has an edge (17, 18), the edges being contiguous when the parts are assembled together. Each edge is formed with first and second portions (23, 21) which are received in a rebated recess of a tubular connector element (24). The two body parts can be flexed apart to insert contents but are prevented from separating by the edge formations, the first portions (23) resisting separation of the body parts at least when they are partly separated, whilst the second portions (21) prevent lateral removal from the recess of the tubular connector element (24). The body parts (10, 11) may be moulded in one part, and later separated. <IMAGE>

Patent GB-2264799-A (GB)
Title: Slow memory refresh in a computer with a limited supply of power
Inventor: REDDY CHANDRASHEKAR M
IPC: G06F1/32
Filed: 1993-03-19
Abstract: A power suspend mode activates a slow DRAM refresh in a computer system (10) with a limited source of power. The power suspend (100) mode reduces the power consumed by the computer system (10) while preserving the contents of memory. The cyclic refresh of DRAM (80) using a slow refresh clock substantially reduces the power consumed while the computer is suspended. This technique is particularly useful for battery powered portable computer systems. When an external or internal condition causes the computer system to transition to a power down mode, an IO subsystem (30) notifies the CPU (20) which sets control bits in the IO (30) subsystem and a video subsystem (40). The IO subsystem (30) then begins to generate a slow DRAM refresh pulse (91). Once the CPU (20) and video subsystem (40) sense the power suspend mode activation, the system memory (80) and video memory (50) are refreshed using the slow refresh clock. The power consumed during the refresh process is thereby greatly reduced. When a resume signal is received by the IO subsystem (30), the slow refresh clock (91) is terminated and the system memory (80) and video memory (50) are again refreshed using a normal faster clock.

IPC: D05C15/22
Filed: 1994-06-17
Abstract: A clip (12) is removably mounted adjacent a hook (11) on a hook bar of a tufting machine. The shank (13) of the clip (12) is removably located in a cut-out (19) formed in the shank (18) of the hook (11). Detent means (21, 22) retain the clip in position.

Title: Cyclic oligomers of substituted cyclic ethers
Inventor: DESAI HEMANT JASHBHAI
IPC: C08K5/159
Filed: 1995-07-10
Abstract: A method of producing cyclic oligomers of substituted cyclic ethers involves the slow addition to a solution of the ether in a relatively polar organic solvent such as dichloromethane or dichloroethane, of a stable protonic acid such as HBF 4 or a cationogenic species for example triethyloxonium tetrafluoroborate or an alcohol in conjunction with a stable Lewis acid such as boron trifluoride etherate. The cyclic oligomer product is isolated from other reaction products, in particular the straight chain oligomers, by extraction with a non-polar solvent, hexane being preferred. The cyclic products are effective plasticisers for polyether polymers, particularly where the cyclic ether is related to or even the same as the ether in the polymer since compatability of the materials is then very likely and separation out of plasticiser unlikely to occur. The oligomers could also have utility as additives in hydrocarbon fuels to enhance combustion and reduce undesirable emissions.
Patent GB-2303199-A (GB)
Title: Valve assemblies
Inventor: BENTLEY BERNARD MARK
IPC: F16K31/122
Filed: 1995-07-12
Abstract: Opening of a valve is achieved by passing pilot air from an inlet 12 through a passageway 13 to act upon the enlarged under face 14 of a piston head 7. This is sufficient to overcome the bias of a spring stack 6 and pressure applied to a balanced stem head 11 so that a valve seal 4 is lifted off a valve seat 5. When the supply of pilot air is removed the pressurised air acting on the face 14 will bleed off again through the entry port 12 so that the valve will close again under the bias of the spring stack 6 and the pressure on the balanced stem area 11. A valve port 15 prevents high pressure air from entering into the low pressure actuation region behind the face 14, by leakage in the event of failure. The valve may be used as a drain valve in a pressurized vessel where the valve is actuated by means of a float valve in the vessel (figure 3).
